pseries: Fix initialization of sPAPREnvironment structure
Since we added PCI support to the pseries machine, we include a qlist of
PCI host bridges in the sPAPREnvironment structure. However this list
was never properly initialized it. Somehow we got away with this until
some other recent change broke it, and we now segfault immediately on
startup.
This patch adds the required QLIST_INIT(), and while we're at it makes sure
we initialize the rest of the sPAPREnvironment structure to 0, to avoid
future nasty surprises.

qxl: fix guest cursor tracking
(1) If the guest cursor command is empty, don't reload it after migration.
(2) Cleaning the guest cursor when it is released by
the spice server. In addition, explicitly reset the
cursor in spice upon destroying the primary surface
(was done by spice-server implicitly). This will prevent
access to pci memory that was released.

Support running QEMU on Valgrind
Valgrind is a tool which can automatically detect many kinds of bugs.
Running QEMU on Valgrind with x86_64 hosts was not possible because
Valgrind aborts when memalign is called with an alignment larger than
1 MiB. QEMU normally uses 2 MiB on Linux x86_64.
Now the alignment is reduced to the page size when QEMU is running on
Valgrind.
v2:
Instead of using the macro RUNNING_ON_VALGRIND from valgrind.h,
the patch now uses a hack from libvirt which tests for the pre-loaded
vgpreload_*.so shared libraries. This avoids the need for valgrind.h.

Please, note that the RSTATE_IN_MIGRATE state is only set when all the

vscsi: send the CHECK_CONDITION status down together with autosense data
I introduced this bug in commit 05751d3 (vscsi: always use get_sense,
2011-08-03) because at the time there was no way to expose a sense
condition to SLOF and Linux manages to work around the bug. However,
the bug becomes evident now that SCSI devices also report unit
attention on reset.
SLOF also has problems dealing with unit attention conditions, so
it still will not boot even with this fix (just like OpenBIOS).
IBM folks are aware of their part of the bug. :-)

monitor: Prevent sign-extension of 32-bit addresses printed by info mem
Previously, on 32-bit i386, info mem used signed 32-bit int's to store
the page table indexes. As a result, address calculation was done in
32 bits and then incorrectly sign-extended to 64 bits, yielding output
like
ffffffffef000000-ffffffffef031000 0000000000031000 ur-
ffffffffef7bc000-ffffffffef7bd000 0000000000001000 urw
ffffffffef7bd000-ffffffffef7be000 0000000000001000 ur-
This makes these indexes unsigned, which yields correct output
00000000ef000000-00000000ef031000 0000000000031000 ur-
00000000ef7bc000-00000000ef7bd000 0000000000001000 urw

qemu-img: Add cache command line option
qemu-img currently writes disk images using writeback and filling
up the cache buffers which are then flushed by the kernel preventing
other processes from accessing the storage.
This is particularly bad in cluster environments where time-based
algorithms might be in place and accessing the storage within
certain timeouts is critical.
This patch adds the option to choose a cache method when writing
disk images.

ehci: add freq + maxframes properties
Add properties for the wakeup rate and the max number of frames ehci
will process at once.
The wakeup rate defaults to 1000 which equals the usb frame rate. This
can be reduced to make qemu wake up less often when ehci is active.
In case the wakeup rate is reduced or the ehci timer is delayed due to
latency issues elsewhere in qemu ehci will process multiple frames at
once. The maxframes property specifies the upper limit for this.

usb: assert on calling usb_attach(port, NULL) on a port without a dev
with the "usb-ehci: cleanup port reset handling" patch in place no callers
are calling usb_attach(port, NULL) for a port where port->dev is NULL.
Doing that makes no sense as that causes the port detach op to get called
for a port with nothing attached. Add an assert that port->dev != NULL when
dev == NULL, and remove the check for not having a port->dev in the dev == NULL
case.

can handle simultaneously. When this limit is reached the
driver will return -EDOM. So we need to capture this to
enable proper return values here.

Filenames may start with "<protocol>:" to explicitly use a protocol like
nbd. Filenames with unknown protocols are rejected in most of QEMU

tools: Use real async.c instead of stubs
It's wrong to call BHs directly, even in tools. The only operations that
schedule BHs are called in a loop that (indirectly) contains a call to
qemu_bh_poll anyway, so we're not losing the scheduled BHs: Tools either use
synchronous functions, which are guaranteed to have completed (including any
BHs) when they return; or if they use asynchronous functions, they need to call
qemu_aio_wait() or similar functions already today.

* dis-asm.h: Add include for fprintf_function (qemu-common.h).
The standard (now redundant) includes are removed.
* mis-dis.c: The definition of ARRAY_SIZE is no longer needed

v3: don't call reset functions on cpu initialization
There is absolutely no need to call reset functions when initializing
devices. Since we are already registering them, calling qemu_system_reset()
should suffice. Actually, it is what happens when we reboot the machine,
and using the same process instead of a special case semantics will even
allow us to find bugs easier.
Furthermore, the fact that we initialize things like the cpu quite early,
leads to the need to introduce synchronization stuff like qemu_system_cond.
This patch removes it entirely. All we need to do is call qemu_system_reset()
only when we're already sure the system is up and running
I tested it with qemu (with and without io-thread) and qemu-kvm, and it
seems to be doing okay - although qemu-kvm uses a slightly different patch.
[ v2: user mode still needs cpu_reset, so put it in ifdef. ]
[ v3: leave qemu_system_cond for now. ]

audio streaming from usb devices
I have streaming audio devices working within qemu-kvm. This is a port
of the changes to qemu.
Streaming audio generates a series of isochronous requests that are
repetitive and time sensitive. The URBs need to be submitted in
consecutive USB frames and responses need to be handled in a timely manner.
Summary of the changes for isochronous requests:
1. The initial 'valid' value is increased to 32. It needs to be higher
than its current value of 10 since the host adds a 10 frame delay to the
scheduling of the first request; if valid is set to 10 the first
isochronous request times out and qemu cancels it. 32 was chosen as a
nice round number, and it is used in the path where a TD-async pairing
already exists.
2. The token field in the TD is *not* unique for isochronous requests,
so it is not a good choice for finding a matching async request. The
buffer (where to write the guest data) is unique, so use that value instead.
3. TD's for isochronous request need to be completed in the async
completion handler so that data is pushed to the guest as soon as it is
available. The uhci code currently attempts to process complete
isochronous TDs the next time the UHCI frame with the request is
processed. The results in lost data since the async requests will have
long since timed out based on the valid parameter. Increasing the valid
value is not acceptable as it introduces a 1+ second delay in the data
getting pushed to the guest.
4. The frame timer needs to be run on 1 msec intervals. Currently, the
expire time for the processing the next frame is computed after the
processing of each frame. This regularly causes the scheduling of frames
to shift in time. When this happens the periodic scheduling of the
requests is broken and the subsequent request is seen as a new request
by the host resulting in a 10 msec delay (first isochronous request is
scheduled for 10 frames from when the URB is submitted).
[ For what's worth a small change is needed to the guest driver to have
more outstanding URBs (at least 4 URBs with 5 packets per URB).]

Fix sys-queue.h conflict for good
Problem: Our file sys-queue.h is a copy of the BSD file, but there are
some additions and it's not entirely compatible. Because of that, there have
been conflicts with system headers on BSD systems. Some hacks have been
introduced in the commits 15cc9235840a22c289edbe064a9b3c19c5f49896,
f40d753718c72693c5f520f0d9899f6e50395e94,
96555a96d724016e13190b28cffa3bc929ac60dc and
3990d09adf4463eca200ad964cc55643c33feb50 but the fixes were fragile.
Solution: Avoid the conflict entirely by renaming the functions and the
file. Revert the previous hacks.

Avoid thundering herd problem
Broadcast was used so that the I/O threads would wakeup, reset their
ts values and all but one go to sleep, in other words an optimization
to prevent threads from exiting in presence of continuing I/O
activity. Spurious wakeups make the looping around cond_timedwait with
ever reinitialized ts potentially unsafe and as such ts in no longer
reinitilized inside the loop, hence switch to signal is warranted and
this benefits of this particlaur optimization are lost.
(It's worth noting that timed variants of pthread calls use realtime
clock by default, and therefore can hang "forever" should the host
time be changed. Unfortunatelly not all host systems QEMU runs on
support CLOCK_MONOTONIC and/or pthread_condattr_setclock with this
value)

gdbstub: manage CPUs as threads (Jan Kiszka)
This patch enhances QEMU's built-in debugger for SMP guest debugging.
Using the thread support of the gdb remote protocol, each VCPU is mapped
on a pseudo thread and exposed to the gdb frontend. This way you can
easy switch the focus of gdb between the VCPUs and observe their states.
On breakpoint hit, the focus is automatically adjusted just as for
normal multi-threaded application under gdb control.
Furthermore, the patch propagates breakpoint and watchpoint insertions
or removals to all CPUs, not just the current one as it was the case so
far. Without this, SMP guest debugging was practically unfeasible.

Introduce a buffered file wrapper for QEMUFile
This patch introduces a buffered QEMUFile wrapper. This allows QEMUFile's to be
rate limited. It also makes it easier to implement a QEMUFile that is
asynchronous since the current QEMUFile API requires that all reads and writes
be synchronous.
The only real non-obvious part of the API is the "frozen" concept. If the
backend returns EAGAIN, the QEMUFile is said to be "frozen". This means no
additional output will be sent to the backend until the file is unfrozen.
qemu_file_put_notify can be used to unfreeze a frozen file.
A synchronous interface is also provided to wait for an unfreeze event. This is
used during the final part of live migration when the VM is no longer running.

Handle terminating signals (Gerd Hoffmann)
This patch makes qemu handle signals better. It sets the request_shutdown
flag, making the main_loop exit and qemu taking the usual exit route, with
atexit handlers being called and so on, instead of qemu just being killed
by the signal.
To avoid calling vm_start() from the signal handler main_loop() got an
additional check so qemu_system_shutdown_request() works even when the
vm is in stopped state.

linux-user: Propagate siginfo_t through to handle_cpu_signal()
Currently all the architecture/OS specific cpu_signal_handler()
functions call handle_cpu_signal() without passing it the
siginfo_t. We're going to want that so we can look at the si_code
to determine whether this is a SEGV_ACCERR access violation or
some other kind of fault, so change the functions to pass through
the pointer to the siginfo_t rather than just the si_addr value.

spapr_cpu_core: instantiate CPUs separately
The current code assumes that only the CPU core object holds a
reference on each individual CPU object, and happily frees their
allocated memory when the core is unrealized. This is dangerous
as some other code can legitimely keep a pointer to a CPU if it
calls object_ref(), but it would end up with a dangling pointer.
Let's allocate all CPUs with object_new() and let QOM free them
when their reference count reaches zero. This greatly simplify the
code as we don't have to fiddle with the instance size anymore.

Makefile: use $(MAKE) variable
For some systems (i.e. FreeBSD) the default 'make' is not compatible with the
GNU extensions used by QEMU makefiles.
Calling the GNU make (gmake) works, however the help displayed refers to the
host 'make' and copy/paste leads to lot of unobvious errors:
$ gmake check-help
[...]
make check Run all tests
$ make check
make: "Makefile" line 28: Missing dependency operator
make: "Makefile" line 37: Need an operator
make: "Makefile" line 41: warning: duplicate script for target "git-submodule-update" ignored
make: "rules.mak" line 70: warning: duplicate script for target "%.o" ignored
make: Unknown modifier ' '
make: Unclosed substitution for eval modules (= missing)
make: "tests/Makefile.include" line 24: Variable/Value missing from "export"
make: "tests/" line 1: warning: Zero byte read from file, skipping rest of line.
make: "tests/" line 1: Need an operator
make: "Makefile" line 660: warning: duplicate script for target "ifneq" ignored
make: "Makefile" line 78: warning: using previous script for "ifneq" defined here
make: Fatal errors encountered -- cannot continue
Using the $(MAKE) variable, the help displayed is consistent with the 'make'
program used.

util/async: use atomic_mb_set in qemu_bh_cancel
Commit b7a745d added a qemu_bh_cancel call to the completion function
as an optimization to prevent it from unnecessarily rescheduling itself.
This completion function is scheduled from worker_thread, after setting
the state of a ThreadPoolElement to THREAD_DONE.
This was considered to be safe, as the completion function restarts the
loop just after the call to qemu_bh_cancel. But, as this loop lacks a HW
memory barrier, the read of req->state may actually happen _before_ the
call, seeing it still as THREAD_QUEUED, and ending the completion
function without having processed a pending TPE linked at pool->head:
worker thread | I/O thread
------------------------------------------------------------------------
| speculatively read req->state
req->state = THREAD_DONE; |
qemu_bh_schedule(p->completion_bh) |
bh->scheduled = 1; |
| qemu_bh_cancel(p->completion_bh)
| bh->scheduled = 0;
| if (req->state == THREAD_DONE)
| // sees THREAD_QUEUED
The source of the misunderstanding was that qemu_bh_cancel is now being
used by the _consumer_ rather than the producer, and therefore now needs
to have acquire semantics just like e.g. aio_bh_poll.
In some situations, if there are no other independent requests in the
same aio context that could eventually trigger the scheduling of the
completion function, the omitted TPE and all operations pending on it
will get stuck forever.
[Added Sergio's updated wording about the HW memory barrier.

sparc32_dma: remove is_ledma hack and replace with memory region alias
This hack originated from before the memory region API was introduced, and
increased the size of the ledma DMA device to capture incorrect accesses
beyond the end of the ledma device. A full analysis can be found on Artyom's
blog at http://tyom.blogspot.co.uk/2010/10/bug-in-all-solaris-versions-after-57.html.
With the memory API we can now simply alias the incorrect access onto its
intended destination allowing us to remove the hack.
